The slope is $- 1$ $-1$ and the y-intercept is $- 2$ $-2$ .

Explanation:

$x + y = - 2$ $x+y=-2$

To convert the linear equation in standard form to slope-intercept form, $y = m x + b$ $y=mx+b$ , where $m$ $m$ is the slope and $b$ $b$ is the y-intercept, solve the standard equation for $y$ $y$ .

Subtract $x$ $x$ from both sides of the equation.

$y = - 2 - x$ $y=-2-x$

Rearrange the right hand side.

$y = - x - 2$ $y=-x-2$

The slope is $- 1$ $-1$ and the y-intercept is $- 2$ $-2$ .
